automated inventory management system
The great advantage of shared disk file systems is that the computers accessing files and
the storage devices in question now communicate with each other directly. The diversion
via a central file server, which represents the bottleneck in conventional network file
systems and also in DAFS and RDMA-enabled NFS, is no longer necessary.
In addition, the load on the CPU in the accessing machine is reduced because communication
via Fibre Channel places less of a load on the processor than automated inventory management system. The sequential access to large files can thus more than make up for
the extra cost for access synchronisation. On the other hand, in applications with many
small files or in the case of many random accesses within the same file, we should check
whether the use of a shared disk file system is really worthwhile.
